Solution

1. Preparation

Gather tools required for the repair.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery and allow at least 15 minutes for the residual energy to dissipate before working on the airbag system.

2. Check and Replace Fuses

Locate the fuse box and identify the airbag system fuses.
Use a multimeter to test each fuse for continuity.
Replace any blown fuses with fuses of the same amperage.

3. Inspect and Repair Wiring

Remove trim panels to access wiring harnesses connected to the airbag system.
Inspect wiring for fraying, corrosion, or loose connections.
Repair or replace damaged wiring as necessary, ensuring all connectors are secure.

4. Reset Airbag Light

After repairs, reconnect the battery.
Use the OBD-II scanner to clear any stored airbag fault codes.
Ensure the airbag light turns off after the reset.

5. Final Checks

Conduct a self-diagnostic test of the airbag system using the scanner to confirm that all systems are operational.
Ensure that the airbag light remains off during the ignition cycle.
